I just bought the SLG about 6 months ago. Its been used 10 times. Each time I put in the tank, air flows out from the hose that connects to the regulator. After a few twists of the hose, the air stops leaking. this has been my way of fixing it every time. Today, I put the tank in and did the usual..air kept coming out and the hose literally popped out from the regulator. Is this an easy fix or should I send it to the shop?
